ROSSING MACHINE Louis Philippe Gagn, Rang Fournier, Anse Ste. Anne Des Monts, Quebec, Canada Filed July 28, 1 958, Set. No. 151,535

- 2 Claims. 01. 144-208) This invention relates to a rossing machine for removing the bark from logs.

One important object of'the invention is to provide a novel machine of the class having :knife carrying members driven through a transmission in which such members may be adjusted along a log without interfering with or interrupting the transmission of power.

A second important object of the invention is to provide a novel machine in which the knife carrying members may be adjusted vertically to operate on logs of different diameters without requiring any change in the transmission mechanism.

A third important object of this invention is to provide a machine for this purpose having a novel log supporting means.

A fourth important object of the invention is to provide a novel knife driving means in such a device.

A fifth important object of the invention is to provide a novel means for rotating, on its axis, a log held in such a machine.

With the above and other objects in view, as will be presently seen, the invention consists in general of certain novel features of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and particularly set forth in the appended claims.

In the drawings like characters of reference indicate like parts in the several views, and:

Fig. 1 is a plan view of a machine embodying this invention.

Fig. 2 is a side view of the device with certain parts omitted to better show those disclosed.

Fig. 3 is a transverse detail view of a log turning mechanism embodied in this machine.

Fig. 4 is a section on the line 4-4 of Fig. 1.

Fig. 5 is a side elevation of a knife carrying member removed from the machine.

Fig. 6 is a section on line 6-6 of Fig. 1; and

Fig. 7 is a view of the knife carrier taken at a right angle to Fig. 5.

In the construction of this machine there is provided at one end a set of supports or legs 1 and at the other end a similar set 2, it being noted that one of each set is located on the longitudinal median line of the machine. These centrally disposed legs are fitted telescopically on the upright members 4 and 5 of the frame, the front and rear posts 1 and 2 being connected by tie rods 3. The tie rods 3 are connected at their ends by cross tie 3a. The uprights 4 and 5 are provided at their lower ends with vertically spaced openings for insertion of a pin 6 engaging the top of posts 1 and 2 as a limit stop, the pin being secured from loss by a chain 7.

A rod 8 extends from end to end of themachine and is fixed to the posts 4 and 5 as by bolts 8a. A longitudinal frame member 9 extends from end to end of the machine and is connected to the bar 8 at one end by an end frame member 10 and at the other end by a table or platform 11. Carried by the frame and located at the front or operators side of the machine there is a V-shaped log support 13 at one end of the machine and a similar support 12 at the other end of the machine. A base member 11a is provided at the rear of the platform 11 and on this base member is mounted the driving means for the power transmission device here shown as an electric motor 14. This motor may have a gas engine substituted there but in either case the part 14 is provided with a shaft 20 carrying a drive pulley -19. Bearings 15 are fixed to the frame and support a shaft 16 on which is fixed a pulley 17 connected to the pulley 19 by a belt 18. On the shaft 16 is also fixed a pulley 17a grooved to receive a transmission cable 21. Bolted to the bar 8 by bolts "8b is a pad 24 from which extends a shaft 23 whereon is rotatably mounted a V-grooved pulley 22 around which the cable 21 extends. Pivoted to the pad is an arm 25 which carries on its free end a tensioning roll 26 under which the cable 21 passes.

Supported by roller 27 for transverse rocking movement and for longitudinal movement on the bar 8 is a platform 28 from which depends a pair of spaced bearings 30 wherein is supported a shaft 29 on which is fixed a grooved pulley 31 which extends freely through slot 28' made in platform 28. The platform 28 also supports a frame 32 on which is mounted a pair of shafts 32a carrying idler pulleys 33 the arrangement being such that the cable 21 runs under one pulley 33, over the pulley 31 and under the other pulley 33 as shown in Fig. 6. With this arrangement, no matter at what position the platform 28 is placed, the shaft 29 will be properly driven.

Fixed on the shaft 29 is a drum 34 having slots 36 in its peripheral portion wherein are mounted knives 35 having projecting cutter edges and being detachably secured by bolts 35m. The drum is covered by a chip catcher, 38. Fixed to the platform 28 at its forward end is an operating handle 37 for use by the operator in moving the platform and cutter longitudinally of the log 39. Adjacent the front of the machine the frame carries a nut 40 wherethrough extends a screw 41 provided with a head 42 engageahle with the end of the log 39.

Adjacent the front of the machine there is provided a pair of posts 43 and 44. On the post 43 is mounted an angle lever 45. The post 43 carries a pin 43a on which is rotatably mounted a pulley 46. Over the pulley 46 passes a cable 47 one end of which is attached to one end of a blade 49 having its other end attached to the short arm of the lever -45. The other end of the cable 47 is provided with a counterweight 48. The blade 49 thus passes beneath the log and has its upper edge provided with a set of rearwardly inclined long sharp teeth 51 which as the blade is moved by the lever 45 will engage and rotate the log.

In operation a log is placed on the supports 12 and 13. The platform 28 is positioned where desired by the operator along the log. The platform 28 being rockably mounted on the bar 8 has its front end rocked downwardly so that the knives, which have been started in rotation by the action of the motor and transmission, will engage on the log and strip the bark from it.

What is claimed is:

1. In a bark removing machine, an elongated frame, log supports fixed at opposite ends of the frame for supporting a log longitudinally of the frame, a bar fixedly supported by the frame and extending longitudinally and substantially medially thereof at substantially the level of a log supported by said log supports, a platform extending transverse the frame, a pair of aligned rollers mounted underneath said platform intermediate its ends and in rolling engagement with said bar for supporting said platform for rocking movement transversely of the bar and for longitudinal movement relative to said bar and frame, a shaft rotatably mounted beneath said plat- P silwer form and carried thereby, a drum provided with cutter knives secured to one end of said shaft and disposed on one side of said bar for engagement with a log supported by said log supports, a driven pulley secured to the other end of said shaft and disposed adjacent said bar on the side thereof opposite the side of said drum, an endless transmission cable trained over said driven pulley and extending alongside said bar, pulleys rotatably mounted at both ends of said frame and including a driving pulley, said cable being trained on said pulleys, idler pulleys carried by said platform on each side of said driven pulley and engaging said cable for maintaining the same in frictional driving engagement with said driven pulley, a motor fixedly secured to one end of the frame and connected to said driving pulley for driving the same, and a second bar fixedly supported by the frame, parallel to the first named bar and disposed underneath the end portion of said platform opposite its drum carrying end.

2. The machine of claim 1 further including manual means for rotating a log supported by said log supports, said manual means including a blade mounted to pass underneath a log held in said supports and having long inclined teeth along its upper edge, a cable attached to one end of said blade and trained over a pulley, a counterweight attached to said cable so as to exert an upward pull on said blade to maintain the same in engagement with said log, and an angle lever pivoted on said frame intermediate its ends and pivotally connected at one end to the other end of said blade for reciprocating the same.
